JOHN HOLTZMAN AND LOUIS GEFON, OF NEW YORK, N. Y.

GAS-LIGHTER.

Specification of Letters Patent.

Patented Mar. 17, ILQMR Application filed April 10, 1912. Serial No. 689,884.

To all whom it may concern Be it known that we, JOHN HoL'rznAN and Lows Garcon, sub ects of the Czar of Russla, residing at New York, in the county of New York and State of New York have lnvcnted new and useful Improvements 111 Gael-lighters, of which the following is a specification.

This invention relates to gas lighters and has for its object a simple automatic device adapted to be fitted at the upper end of the burner to create a spark to light the gas when turned on, and it consists of new and simple means which will. be more fully de-- scribed in the following specification, set forth in the claim and illustrated in the drawings, where n Figure 1 is aside elevation. Fig. is an end view. Fig. 3 is a detail sectional view.

The device is clamped to the upper end of the burner 5 by means of the metal band and set screw 7, the band carrying at it outer end a tube 8 threaded at its lower and to receive an adplsting screw. ithm the tube and above the screwl) is a spring to, carrying on its upper end a block] I ot'spark producing sno -nice and extending upward from the tube 10 are arms 12 having a short shaft 13 journaled in their upper ends. This shaft 13 carries a cam. llsci-rated on its edge and having a handle 1-5 projecting therefrom. As the handle is raised the serrations are carried across the block 11 and upon the downward movement of the handle 15, sparks are made and thrown toward the tip ot' the burner 5. As the handle 15 1s moved upward, tension is created in a spring 10 which surrounds the shaft 13 and is connected with one arm 12 and with the handle 15, and as the handle 1s carried upward and released, the tension of thesp'ring throws the arm downward to procluce'the desired result. The convolutions of the spring are nterposed between the cam 14: and the adaeent arm 12 so asto form means for holding the cam in proper position with rcla v tion to the spark producing substance to in sure maximizing the friction between the substance and the serrated edge of the cam;

As the block of spark producing substance becomes worn, the screw Smay be so adjusted as to exert a prcsure on same to-crcite sullicient friction from the cam li'to cause the s iarkiug'.

l is obvious that the parts may be otherarrangcd and applied to a gas burner without departing from the essential 't'ea- [.lll'trv' above described.

What 'we claim as new is A gas lighter comprising a support adaptodto be secured to a burner, a cylinder providednrpon the support and havingspaced arms mounted at its end, a pyrophoric ma;
